The effect's display/registration name.
Used as the fallback identifier by SlashCo.RegisterEffect when its name argument is omitted (name = name or table.Name).

Multiplier for how fast a generator fuels while this effect is active on the player; divides the generator's DefaultTimeToFuel.
Checked through Player:ItemValue/Player:PerkValue, which look at active effects before either item slot - so this overrides any ITEM.FuelSpeed set by a held item while the effect is active. Used by the Buzzed, FuelSpeed, Balkan/BalkanTrip and BalkanTripWeak effects.

function(ply)
Called by Player:AddEffect right after the effect becomes active on the player (after any earlier expiry handling has already run).

function(ply)
Called when the effect naturally times out and no other stacked instance of it remains active, or as the fallback used in place of EFFECT.OnRemoved when that isn't defined (whether the effect is re-applied while active, or explicitly cleared).

function(ply)
If defined, called instead of EFFECT.OnExpired whenever the effect is removed early - re-applied while already active (via Player:AddEffect), or explicitly cleared via Player:ClearEffect/Player:ClearEffects.

function()
Dispatched client-side via Player:ItemFunction every frame while the local survivor is alive, to draw custom post-processing/screen effects. Takes priority over the equivalent field on either of the player's items. Used by almost every shipped effect (e.g. Speed, Invisibility, Awareness, Dazed).

function(ply) -> suppress
Dispatched via Player:ItemFunction, checked before the player's item. If it returns a truthy value, the player's footstep sound (and the "step notice" visual the Slasher would otherwise perceive) is suppressed. Used by Invisibility.

function(ply) -> visible
Dispatched via Player:ItemFunction, checked before the player's item, to override whether the player can currently be seen. Used by Invisibility to return false.

function(ply, dmg) -> result
Dispatched via Player:ItemFunction, checked before the player's item, whenever the player takes damage. Can mutate dmg in place (e.g. dmg:ScaleDamage(...)); if it returns a non-nil value, that value is returned from the gamemode's EntityTakeDamage hook. Used by Resistance to scale incoming damage down.

function(ply) -> canSee
Same dispatch as EFFECT.CanBeSeen, overriding whether the player can see other players' flashlights. Not currently used by any shipped effect.

function(ply) -> dontTickLife
Dispatched via Player:ItemFunction, checked before the player's item, when the player dies. Returning a truthy value skips the entire normal death sequence, the same as the identical field on ITEM. Not currently used by any shipped effect.

function()
Dispatched client-side via Player:ItemFunction while halos are being drawn for the local survivor. Not currently used by any shipped effect.

function() -> useThirdperson
Dispatched via Player:ItemFunction from CalcView, checked before the player's item, to decide whether to use a custom third-person camera. Not currently used by any shipped effect.

function(ply, secondaryItem) -> dontDrop
Dispatched via Player:ItemFunction, checked before the player's primary item, right before the player's secondary item is dropped; returning a truthy value cancels the drop. Not currently used by any shipped effect.

function(ply, item, itemindex) -> dontPickup
Dispatched via Player:SecondaryItemFunction, checked before the player's secondary item, right before a new primary item is picked up; returning a truthy value cancels the pickup. Not currently used by any shipped effect.

function(ply, item, itemindex) -> dontPickup
Dispatched via Player:ItemFunction, checked before the player's primary item, right before a new secondary item is picked up; returning a truthy value cancels the pickup. Not currently used by any shipped effect.
